Produced by Prodigy Pictures, its exec producers are Jay Firestone, Mallozzi, Mullie and Vanessa Piazza. A 13-episode second season will premiere in 2016.

“With its mysterious premise and fascinating characters, Dark Matter has built an incredibly loyal, passionate and engaged fan base,” said Chris Regina, Syfy’s senior VP of program strategy. “We look forward to another out-of-the-world season from this talented creative team.”

“Killjoys” is about a trio of bounty hunters who chase deadly Warrants (or fugitives) throughout a distant planetary system on the brink of a bloody class war. From Temple Street Productions and creator-showrunner Michelle Lovretta, it is produced in association with Space and distributed worldwide by Universal Cable Productions. It stars Hannah John-Kamen, Luke Macfarlane and Aaron Ashmore as hunters Dutch, D’avin and John.

“With exciting space-based action, deep world building, and a standout cast, ‘Killjoys’ has struck a nerve with viewers and critics alike,” said Bill McGoldrick, Syfy’s exec VP of original content. “We can’t wait to see what adventures Michelle Lovretta and Temple Street take Dutch, John and D’avin on in season two.”

A second 10-episode season of “Killjoys” will also air in 2016.

“We couldn’t be more excited to bring back ‘Killjoys’ and its stellar cast to audiences across the U.S.,” said David Fortier and Ivan Schneeberg, co-presidents of Temple Street Productions, who exec produce the series along with Lovretta and Karen Troubetzkoy. “We look forward to working with the team at Syfy for a thrilling second season.”

Syfy’s upcoming lineup includes December premieres of “Childhood’s End,” an event series, based on the Arthur C. Clarke novel, that has a cast that includes Charles Dance and Mike Vogel, and “The Expanse,” which is based on Daniel Abraham and Ty Franck’s book series and stars Thomas Jane and Steven Strait.
